Young Hindu priests perform a ritual during the Janai Purnima festival at the Pashupatinath Temple in Kathmandu, Nepal on Aug. 26, 2018. During this festival, Hindus take holy bath and perform annual change of the Janai, a sacred cotton string worn around their chest or tied on the wrist, in the belief that it will protect and purify them.
